On Saturday around 9:30 a.m. a man was allegedly shot and killed near the 600 block of Sycamore Street.

Police said he was pronounced dead at the scene, and have not released the name of the victim.

"Again, another senseless violence in our city," Armstrong told reporters. "Obviously so tragic to lose three people in one incident."
